gp for kids-urgent!!!

hi all
I'm looking for a good GP thats excellent with babies and toddlers in or around Sandton .... someone who actually takes their time to see whats wrong with the little ones. so fed up with all these doctors who ask you whats wrong and brush aside all your worries with "its just a bug in the air" although you know your baby best and something is really wrong. I also cant just go to a paed coz my med aid says you have to go to a GP first.
